Kodak No.2 Brownie brand_Cinestill and the outer thread isThe Kodak No. 2 Brownie is ancient: it's the first camera ever made to use 120 film, way back in 1901. This one is slightly newer than that, from about 1924 1931, but still, that's 100 years old, give or take. And it's in great shape: it works perfectly, cosmetic condition is near new, and it even includes its original box (though that's a bit rough) This is not just an antique: it's a totally usable camera that you can shoot today. And you should!
